Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the inclusive production rates of K[sub s], A and X hadrons produced in e[sup +]e[sup [minus]] annihilation at the Z[sup 0] pole. The analysis is based upon approximately 50K Z[sup 0] decays collected in the SLD experiment at SLAC in 1993. The observed rates of (K[sub s]) = 1.02 [plus-minus] 0.02 [plus-minus] 0.09 and ([Lambda]) + ([bar [Lambda]]) = 0.38 [plus-minus] 0.01 [plus-minus] 0.04 are consistent with previous measurements. Our differential cross section peak-position results are shown to be consistent with QCD predictions based on the modified leading logarithm approximation and local parton-hadron duality.

Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the inclusive production rates of K{sub s}, A and X hadrons produced in ee− annihilation at the Z° pole. The analysis is based upon approximately 50K Z° decays collected in the SLD experiment at SLAC in 1993. The observed rates of (K{sub s}) = 1.02 ± 0.02 ± 0.09 and ([Lambda]) + ({bar {Lambda}}) = 0.38 ± 0.01 ± 0.04 are consistent with previous measurements.

Book Synopsis Preliminary Measurement of Leading Particle Effects in Hadronic Z[sup 0] Decays by :
Download or read book Preliminary Measurement of Leading Particle Effects in Hadronic Z[sup 0] Decays written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary evidence for leading particle production in hadronic decays of the Z[sup 0] to light quark pairs using 150,000 events recorded in the SLD experiment at SLAC. The highly polarized electron beam produced by the SLC is used to tag quark and antiquark jets, and a signed impact parameter technique is employed to reject heavy flavor events. Charged hadrons are identified in the SLD Cherenkov Ring Imaging Detector (CRID) and[Lambda]/[bar[Lambda]] are reconstructed using their charged decay modes. In a high purity sample of quark jets, the baryon momentum spectrum is harder that that of the antibaryon, and conversely for a sample of antiquark jets, supporting the hypothesis that the faster particles in jets are more likely to carry the primary quark or antiquark from the Z[sup 0] decay. Similarly, more high momentum K[sup -] that K[sup+] are observed in quark jets and conversely for antiquark jets, consistent with the hypothesis that leading K[sup[+-]] are produced predominantly in s[bar s] events rather than[ital u][bar[ital u]] events.

Download or read book Production Of[pi][sup[plus-minus], K[sup[plus-minus], P, K[sup 0][sub S], [Lambda][sup 0], K[sup*0] And[phi] in Hadronic Z[sup 0] Decays written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Production rates and momentum distributions have been measured for[pi][sup[+-]], K[sup[+-]], p, K[sup 0][sub s], [Lambda][sup 0], K[sup*0] and[phi] in 150,000 hadronic Z[sup 0] decays recorded by the SLD detector at the SLD collider at SLAC. The analysis uses the SLD Cerenkov Ring Imaging Detector (CRID) for clean and efficient identification of charged tracks and significant background reduction. In addition, K[sup*0] production has been studied in quark and anti-quark jet samples, which were identified by their electroweak forward backward asymmetries using the SLD high electron beam polarization. A difference between the two samples is observed in the K[sup*0] rate at high momentum, consistent with leading particle and strangeness suppression hypotheses.
